Dear Kell, These sure look like Crab Lice, Phthiris pubis, to us. BugGuide only has a few images and very little information. You can learn more about this human parasite on the Penn State Entomology site where it states: “These lice are found mostly in the hair of the pubic area. They may also be found under the armpits, in the beard or mustache and on the eyebrows and eyelashes. Their development from egg to adult normally requires from 30 to 41 days. Adult crab lice live about 30 days. Females deposit 30-50 eggs (in her lifetime).”
